Description
Electric central locking actuator for the right rear door for Peugeot 307. Rear passenger-side door.
Product Overview
Replacement electric door lock for the right rear (rear passenger-side) door of the Peugeot 307, commonly referenced under part number 9138G0. Designed for mechanics and experienced DIYers who need a reliable central locking actuator to restore door locking and unlocking functions. Ideal when the door no longer locks or unlocks properly from the remote or central locking system, or when the mechanical latch fails to operate smoothly.
Key Benefits
- Direct fit for Peugeot 307 applications — simplifies repair and reduces installation time.
- Restores central locking function and mechanical latch operation.
- Saves labor compared with repairing internal actuator components.
- Commonly searched by part number 9138G0 for quick online findability.
How It Works
The unit integrates an electric actuator and mechanical latch. When the central locking signal is received, the actuator moves the latch mechanism to lock or unlock the door. The assembly also provides the mechanical catch for the door striker and interfaces with interior and exterior handle linkages.
Replacement Procedure
Recommended steps for professionals and competent DIYers:
- Disconnect the negative battery terminal before starting to avoid electrical shorts and accidental lock activation.
- Remove the inner door trim and vapor barrier to access the lock assembly. Keep screws and clips organized.
- Disconnect the electrical connector and any rod/linkage from the lock mechanism. Note the positions of linkages for reassembly.
- Remove the mounting bolts securing the lock to the door shell and extract the old unit.
- Fit the replacement lock, reconnect linkages and electrical connector, then temporarily reconnect the battery to test locking/unlocking and handle operation.
- Verify smooth operation (remote lock/unlock, interior/exterior handles, child lock if present) before reassembling the door trim and sealing the vapor barrier.
- Final check: cycle the lock several times and inspect for binding or unusual noise.
Mounting Recommendation
Use correct hand tools (Torx/Spline/Phillips as required) and torque settings for fasteners. Ensure door moisture barrier is re-sealed to prevent water ingress. Lubricate moving latch points with appropriate light grease and avoid forcing linkages into position. Re-test all functions before completing reassembly.
Why This Part Most Often Fails
Failures are typically caused by a combination of mechanical wear and environmental exposure. Common failure modes include:
- Water ingress and corrosion affecting the motor, gears or electrical contacts.
- Worn plastic gears or mechanical linkages that strip or break after many cycles.
- Electrical connector corrosion or intermittent wiring faults.
- Mechanical damage from forced operation or misalignment after previous repairs.
Failures become more likely on high-mileage vehicles or in regions with frequent moisture exposure.

Notes For Professionals
This part is intended for fitment into the right rear door (rear passenger-side) of Peugeot 307 models. Confirm correct alignment of linkages during installation to prevent premature wear. When in doubt during removal or reassembly, document existing linkage positions to ensure accurate reattachment.
